Just about any user operation should support Undo, since most of them make changes that are difficult to manually recover from. For instance, all three ops on the main screen - stopping timers, advancing to the next timer, and adding time to the current timer - alter the time remaining in a way that can't be easily undone by the user.

This issue is to track the changes in the main screen (listed above), since those are the ones that are the hardest to manually undo. A separate issue will track undoing changes in the Settings screen.

Useful for interval training, when people may have different sets they use on different days.

When the user silences a notification with the lock or home buttons, or ignores the alarm, add a feature to take that as a snooze.

Similar to #1, the settings screen operations should support Undo. This is more a matter of completeness than anything seriously impacting usability, since the Settings screen options that are difficult to undo by hand (such as deleting a timer) are not easily performed by accident.
